Abstract: METHOD AND APPARATUS FOR REDUCING          THE TEMPERATURE OF BAKERY PRODUCTS                Abstract of the Disclosure Method for reducing the temperature of bakery products immediately after the discharge thereof from the oven, by means of vacuum.  The bakery products are first subjected to a substantially linear pressure reduction as a function of time at a rate of not more than 60 mm Hg per second through at least half of the total pressure drop employed.  The pressure reduction rate is then allowed to increase substantially for terminating vacuum treatment.          Apparatus for carrying out the method comprises at least one vacuum chamber adapted to be connected to a source of vacuum through a vacuum conduit and a valve, and a closeable opening for bringing bakery products into and out of the chamber.          In the vacuum conduit in parallel to a servo-valve serving to applying full vacuum effect from the source of vacuum during said remaining portion of the total pressure drop, there is inserted a by-pass conduit having a permanently open flow cross-section adjusted to give said substantially linear pressure reduction.

Abstract: Abstract of the Disclosure Both the operative position of a movable platen and the presence of paper to be advanced past the platen in a line at a time printer are affirmatively sensed by a  single mechanism.  A cantilevered spring arm exten-ding from a fixed mount includes a terminal switch sensor at its free end in proximity to the paper.  At an intermediate region along its length the spring arm traverses adjacent to but spaced apart from the platen, and an adjustable set screw on the arm is disposed for contact with the platen.  When the platen is in operative position, behind the print hammers, and the printer is loaded with  paper, the spring arm biases the actuator into contact with the paper, transferring the switch contact to a given position and thereby indicating that both needed prerequisites for printer operation are satisfied.  If the platen is disengaged from its normal posit on, as for paper loading, the spring arm is concurrently moved away from the paper and the switch actuator freed to transfer the switch to its opposite contact.  In the absence of paper the switch actuator is also freed regardless of platen position.  The length of travel of the spring arm is substantially greater than that of the switch actuator and the spring arm has a greater spring force than the switch actuator arm, insuring both forceful operation of the switch despite varia-tions in paper thickness, and easy vernier adjustment of the trip point of the switch.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved self-locking device for locking a movable structural member to a stationary structural member, or to another movable structural member, or for unlocking the same.  This comprises a rotatable self-locking cam and an actuating means therefor; the rotatable self-locking cam is rotatably mounted on a first structural member and has (1) an arcuate surface thereon, capable of preventing movement of a movable strucutral member in a first or opening direction, and (2) a cam surface thereon, capable of moving the movable structural member in the first or opening direction.      The actuating means is capable of rotating the self-locking cam in an angular direction whereby the cam surface contacts an ear on the movable structural member to forcibly move it in the first or opening direction, while the arcuate surface is being simultaneously moved out of the way of the movable structural member, due to the angular rotation of the self-locking cam, to permit the movement of the movable structural member in the first or opening direction to unlock the movable structural member from the first structural member.  Means mounted on the first structural member contacts the self-locking cam and limits the rotation thereof.  Then, the ear on the movable structural member is subsequently capable of rotating the self-locking cam in an angular direction opposite to that of the first angular direction, whereby the movable structural member returns to its original locked position, wherein it is prevented from moving in the first or opening direction by the arcuate surface on the rotatable self-locking cam.

Abstract: GAS PANEL VOLTAGE REGULATOR          ABSTRACT OF THE DISCLOSURE    To compensate for the relatively wide variation in the electrical operating parameters of a gaseous discharge device resulting from varied physical characteristics, the amplitude of the signal used to sustain a discharge is determined, generated and controlled as a function of the physical charactertistics of the panel.  In operation, a plurality of sample cells are used for control purposes, and the sustain signal applied to the sample cells is incremented from zero during each sustain cycle until the sample cells are discharged, to determine the minimum sustain signal Vs min. required to sustain the discharge.          An offset circuit is used to increase the sustain signal by a predetermined amount above the Vs min. level for panel operation, and a voltage regulator is connected in a closed loop arrangement with the sustain generator to automatically adjust the sustain signal to compensate for variation in the physical parameters of the device such as aging.
